    Important

    • Java Development Kit (JDK) 1.8 is applicable to all versions of the TCP client SDK for Java. JDK 1.6 is applicable only to the TCP client SDK for Java 1.8.4.Final and earlier versions. To prevent JDK compatibility issues when you update the SDK version, we recommend that you use JDK 1.8.
